the projectile or ball, "The crtrdgeaismade `up `of `an''outerfsocket 5adapted to be ad-` justed in the 'breech-end Vof the cannon, of an innersocket 5?, adjusted inf` the socket 5,` of a central tubefzsecured to.,the bottom of the socket 5a, `a chargepfjpowderi Lfilling the cartridge,saveitheinner tube 6, and a. priming element 8 being placed in the outerorificejof suchtube."l g v l 1 VThe projectile or ballb comprises acylindrical bodylQ and a reduced forward part `1Q terminatingin front,in an ogive or conicall-.point 11, valso provided l with l s a littlecylindrical prolongation A12, these, parts 9,

10, 11, 12being preferably made'ina single' piece, but which may be madeseveral pieces assembled by screwsor otherwise.`

. Within the projectile or ball are provided twochambersV ljand 14;,separated trom one by a` transverse -partition 15, in which areproviClGCl Several narrow `channels 16, and in thebackchamber 13is;secured s central Atube 17 theinner end: ofwhi'chis closed `while theouter end is open. E 1

In" the periphery ivf luie toay- 9, f 'die projectile-or ball areprovided helicalchanbody, and which arecovered laterallyby a jacket 19adjusted on thesaid body; the rear of such jacket passes .a littlebeyondthe body and 's adapted to be `adjusted in the oriiiceof thesocket 5a?. I

y The result is that in'touching theground orother impediment, the ballproduces a j ,j firstexplosion which will sendit up a few l yards, saveits point which will remain on or inthe impediment. The projectile orball will" fall on the ground andwill place itself ldsubstantially flatin any direction.

yOf` course, the ldierent arrangements andymay be greatly varied withoutchanging the essential characters ofthe invention. It y mustalso beunderstood that the invention l l iis applicable to fire-arms `of allcalibers.

` "Claims: l

l. `A projectile or ball having in its wall` lwhelical channels open atboth their ends, and

`means whereby to l from being traversedby .the` air of the at- X`mosphere during the journey of the ball.

` l@ A projectile or ball having a large cylindrical portion and areduced cylindrical portion, such large portion being provided`vvfithhelica'l channels which open at the rear andthe forward part vofthe said portion,`

and a ring slidable on such reduced portion j ofthe ball and adaptedtoobstruct the forl l. j ward orifices of such helical channels.

3. A projectile or ball having helical "point downward, and that onfalling tra-l.

will drive l to tire the charge of `above described are only` given asexamples rprevent Asuch channels' grooves in its periphery, acylindrical jacket surroundmg such ball and closing laterally suchgrooves,so that the latter form helical channels openonly at the rearand the `forward ends, and means whereby to prevent such channelsfrombeingtraversed by the air of the atmosphere during the journey of theball.

4. A cartridge comprising a socket, apro` jectile or ball adjusted tothe forward part 'y of the socket, charges of powder in the 'socket andin the projectile or ball respectively, and means whereby to fire thecharge of the socket at a point, located at'the forward part Vof thelatter and at the same time the projectile or ball at a point located atthe rear of thejsaid projectile or ball.

5. A cartridge comprising a socket, a projectile or ball adjusted to theforwardpart of the socket, a central tube secured to the bottom of thesocket and extending forwardly, a charge ofpowder inthe ,socket aroundsuch tube, a charge ofpowder in the projectile or ballv wholly in frontofthe charge of the socket, and means whereby to hre such charges ofpowder through the said tube wherebythe combustion will spread from theforward part to the rear in the socket and from the rear to the forwardpart in the projectile or ball.

In testlmony that I claim the foregoing as my invention I have signed myname in presenceV of two subscribing witnesses.
